Productivity of organically enriched ecosystem. - AE0509

R&D Summary Objectives:- Quantify enhanced infaunel productivity levels in areas enriched by fish farm waste and sewage sludge, assess the resultant influence on epifaunal and demersal predatory populations and hence identify the potential pathways for transference of organic material away from the initial sites. Key customer purpose:- Enable the significance of contaminant transference through the food chain to be assessed, leading to improved policy relating to the control of organic waste discharges.
a) To quantify and contrast the productivity of benthic infaunal organisms in areas enriched by fish farm waste and by dumped sewage sludge. b) To assess the influence of enhanced infaunal production in such areas on the distribution, density and production of epifaunal and demersal predatory populations. c) To identify food chain interrelationships and quantify production at successive trophic levels in organically enriched areas and the potential pathways for the transference of material from organically impacted areas. d) To provide a sound scientific basis for estimating the potential for biotic transference of materials associated with organic wastes beyond their initial sites of deposition.
